“…11 The corrected MAP incorporated the AV peak gradient as measured by TTE. 11 Yet again, this assumption has not been validated in humans or in the context of AS. On the other hand, Bombardini et al recommended the addition of the pressure drop to the brachial systolic blood pressure to estimate LV ESP.…”

Background: Studies utilizing invasive pressure-volume loops offer valuable insights into left ventricular (LV) contractility, yet their availability remains limited. Conversely, non-invasive indices are accessible and reproducible; however, their validation in aortic stenosis (AS) is lacking. We sought to validate the non-invasive indices of PVL studies in a group of symptomatic severe AS. Methods: We recruited patients with symptomatic severe AS admitted for trans-catheter aortic valve replacement (TAVR) to undergo invasive PVL studies. Non-invasive PVL indices were measured with three-dimensional (3D) echocardiography with a pre-specified protocol. The agreement between invasive and non-invasive calculation methods were assessed. Results: Eleven patients (11) were recruited for this pilot study. The non-invasive end-systolic pressure-volume relationship (ESPVR) Kelly's method (Ees(sb) = 0.9 x systolic blood pressure/end-systolic volume (ESV)) had the best agreement with invasive ESPVR (limits of agreement -1.7 to 2.1 with a percentage error of 24%, one sample T-test p =0.504). Systolic blood pressure, as measured by the brachial blood pressure cuff, had the best agreement with end-systolic pressure in severe aortic stenosis (limits of agreement -60 to 60 with a percentage error of 3%, one sample T-test p =0.959). Conclusion: Measurement of the single-beat estimate of ventricular elastance (Ees(sb)) is possible in patients with severe aortic stenosis. Kelly's method (Ees(sb) = 0.9 x SBP /ESV) has the best agreement with the invasive measurement of left ventricular elastance (Ees). Systolic blood pressure, as measured by the brachial blood pressure cuff, has the best agreement with end-systolic pressure in severe aortic stenosis.

“… 5 Regarding patients with severe AS; Garcia et al 23 reported the cardiac elastance before and after surgical aortic valve replacement in 6 patients. Yamashita et al 24 reported that 56 patients with severe AS and preserved ejection fraction who underwent TAVR had early improvement in the afterload and LV efficiency, resulting in further decrease in the transvalvular PG without SV deterioration in the early postoperative period when compared with 61 patients who underwent surgical aortic valve replacement. Nevertheless, these reports did not mention the association of VAC with prognosis after the procedure, and we believe that the insight of PV loops’ association with AVR is relatively novel and underreported.…”

Background Ventricular‐arterial coupling predicts outcomes in patients with heart failure. The arterial elastance to end‐systolic elastance ratio (Ea/Ees) is a noninvasively assessed index that reflects ventricular‐arterial coupling. We aimed to determine the prognostic value of ventricular‐arterial coupling assessed through Ea/Ees after transcatheter aortic valve replacement to predict clinical events. Methods and Results We retrieved data on 1378 patients (70% women) who underwent transcatheter aortic valve replacement between October 2013 and May 2017 from the OCEAN‐TAVI (Optimized transCathEter vAlvular iNtervention) Japanese multicenter registry. We determined the association between Ea/Ees and the composite end point of hospitalization for heart failure and cardiovascular death by classifying the patients into quartiles based on Ea/Ees values (group 1: <0.326; group 2: 0.326–0.453; group 3: 0.453–0.666; and group 4: >0.666) during the midterm follow‐up after transcatheter aortic valve replacement. During a median follow‐up period of 736 days (interquartile range, 414–956), there were 247 (17.9%) all‐cause deaths, 89 (6.5%) cardiovascular deaths, 130 (9.4%) hospitalizations for heart failure, and 199 (14.4%) composite events of hospitalization for heart failure and cardiovascular death. The incidence of the composite end point was significantly higher in group 2 (hazard ratio [HR], 1.76; 95% CI, 1.08–2.87 [ P =0.024]), group 3 (HR, 2.43; 95% CI, 1.53–3.86 [ P <0.001]), and group 4 (HR, 2.89; 95% CI, 1.83–4.57 [ P <0.001]) than that in group 1. On adjusted multivariable Cox analysis, Ea/Ees was significantly associated with composite events (HR, 1.47 per 1‐unit increase; 95% CI, 1.08–2.01 [ P =0.015]). Conclusions These findings suggest that a higher Ea/Ees at discharge after transcatheter aortic valve replacement is associated with adverse clinical outcomes during midterm follow‐up.

Background: Studies utilising invasive pressure‒volume loops offer valuable insights into left ventricular (LV) contractility, yet their availability remains limited. Conversely, noninvasive indices are accessible and reproducible; however, their validation in patients with aortic stenosis (AS) is lacking. We sought to validate the noninvasive indices of PVL studies in a group of symptomatic severe AS patients. We recruited patients with symptomatic severe AS admitted for transcatheter aortic valve implantation (TAVI) for invasive PVL studies. Noninvasive PVL indices were measured with three-dimensional (3D) echocardiography with a prespecified protocol. The agreement between invasive and noninvasive calculation methods was assessed. Results: Eleven patients (11) were recruited for this pilot study. The noninvasive end-systolic pressure‒volume relationship (ESPVR) determined by Kelly's method (Ees(sb) = 0.9 × systolic blood pressure/end-systolic volume (ESV)) had the best agreement with the invasive ESPVR (limits of agreement -1.7 to 2.1 with a percentage error of 24%, one sample T test p =0.504).
